i iJCEFIQATIQEq forming part of Letters Patent No. 306,562, datedOctober 14, 1884.

Application filed May 2, 1884.

To all whom, it may concern.-

Be it known that I, WILLIAM E. VINCENT, of Port Deposit, in the countyof 'Cecil and State of Maryland, have invented certain new and usefulImprovements in Machines for Forming Can-Bodies, of which the followingis a specification.

This invention relates to machines for forming the bodies of tin cans;and it consists in the combination of a series of devices, ashereinafter more fully set forth.

I igure 1 is a perspective view of the machine. Fig. 2 is a longitudinalvertical section; Fig. 3, atop plan view. Fig. llSdflOIlh nularprojections 91,

elevation of the rolls shown detached, and Fig. 5 is a perspective viewof the blank for a can-body after being operated upon by the machine,and Fig. 6 is aview showing certain details of construction.

The object of this invention is to produce a machine by which fiatsheets of tin can be given the proper curvature and have the two endsbeveled or flared all at a single operation and with rapidity anduniformity. To accomplish these results I first provide two rollsconstructed as shown in Fig. 5that is to say, one of the rolls B isprovided with anthe inner edges of which are beveled, as shown, andplaced at a distance from each other equal to the length that the bodyof the can is to be. The other roll, 0, is provided with a correspondingset of recesses, at, so that the two rolls will fit close together, asrepresented. The rolls here shown are provided with two spaces ofdifferent lengths, so that sheets of different widths may be operatedupon, and thus make can bodies or blanks of two different heights orlengths on the same machine. It is, however, obvious the rolls may beprovided with more such spaces, and thus adapt the machine to makingstill other sizes, if desired. These rolls thus formed are mounted in asuitable frame, A, each roll being provided with gear-wheels at one end,and the upper roll, B, being mountedin vertically-adjustable boxes 25,which are acted upon by screws Z), as shown in Figs. 1 and 2, so thatthe two rolls can be adjusted in reference to each other as may berequired. In rear of these rolls is seen red a transverse bar, 0, which(N0 model.)

2,and 6.) Upon this bar 0 is secured a plate, 7

I, opposite each space, th rough which the sheet is to be passed, asshown in Figs. 2 and 3, the front edge of these plates I being beveled,so as to fit close against the rear upper side of the lower roll, 0, asshown in Fig. 2, their function being to act as guides to the sheet oftin as it passes through between the rolls and turn it upward. Each ofthese plates I has a set-screw, k, arranged to bear against its rearunder side, as shown in Fig. 2, so that it may be adjusted at differentinclinations and keep its front edge close against the roll 0, and thusinsure the sheet passing above the same. Above the rolls is secured acurved guard or plate, E, as shown in Figs. 1 and 2, the lower edge ofwhich is parallel with and close to the upper roll, as shown, the objectof which is to prevent the curved blank from passing on around the roll.The blank, as it comes up on the rear side of the roll 13, strikesagainst this guard-plate E, and, as it passes entirely from between therolls, is thus thrown out and falls upon the inclined chute F, securedto the frame in rear of the rolls, as shown in Figs. 1, 2. and 3, downwhich they roll into any suitable receptacle.

In order to guide the sheets properly between the rolls, a feed or guideboard, D, preferably of metal, is secured to the frame .directly infront of the rolls, as shown in Figs. 1, 2, and 3. It is provided withvertical sides h, the inner faces of which are placed even with theouter edge of the bevels on the rolls, so as to guide the sheetaccurately on their outer edges, and an adjustable bar, a, is placed ator near the center, and is arrangedtolbe moved laterally sufficiently tobring its outer edges on a line with the edge of the bevels on thecentral portion of the rolls, this bar a having lugs 011 its under side,which project through slots i in the plate D,to hold it in line andadmit of such lateral adjustment. A

traversing or adjusting screw, Z, is mounted in suitable bearingsunderneaththe bed D, and works in a lug, T, which also projects from oris attached to the under side of the guide-bar 5 a through a slot in thebed, the screw Z being provided witha crank or hand wheel for operatingit, and thus adjusting the guide or bar a. It is, however, obvious thatinstead of this the bar may have slots formed transversely in it,through which bolts may project from the bed and be provided withthumb-nuts above; or the guide-bar a may be made of such a width as notto require any adjustment.

If the machine is to be run by power, as is proposed, one of the rollswill be provided with a pulley, as shown in Fig. 3, or with a fast andloose pulley, as may be preferred; but if to be operated by hand it willbe'provided with a crank instead.

first adjust the guide-bar to the one or the other side, according as itis desired to make the longer or shorter blanks or can-bodies,

and then shove the sheets previously cut to' the proper size forwardbetween the guidesa and h until the front end of the sheet enters To usethe machine it is only necessary to chine being very great, as mayreadily be understood. By adjusting theIplates I, so as to give themmore or less inclination, the blank may be curved more or less, asdesired.

I am aware that rolls have before been made with beveled flanges andrecesses, and also thatadjustable guides have been used inconnection-with plain rolls and a shield for throwing out the bent sheetafter it has passed between the rolls, and therefore I do not claim anyof these features, separately considered; but,

Having thus described my invention,what I
